(Source: Reuters) The leading electric car manufacturer Tesla (USA) will again accept vehicles pay in bitcoin when the process of “mining” this cryptocurrency is certified to use clean energy. Tesla CEO, Billionaire Elon Musk announced the above information on June 13 and immediately caused bitcoin to increase 5.1% in value, to $ 37,360.60 at 1:10 am on June 14 (Vietnam time). Billionaire Musk said Tesla will restore use bitcoin coin in payment transactions when “miners” certify that 50% of the electricity used to “mine” cryptocurrencies is clean energy and identify this as a positive trend in the future. Bitcoin and other cryptocurrencies are the “rewards” obtained after the process of “mining” with specialized miners that solve computational problems that allow linking blocks of transactions (blockchains). This process consumes a large amount of energy. In May, billionaire Musk announced Tesla will no longer accept bitcoin as a means of payment in its purchases. The announcement reverses Tesla’s decision in late March to accept payments in bitcoin and invest $1.5 billion in the digital currency. According to the graph of Bitcoin Mining Power Consumption Index produced by the University of Cambridge (CBECI), the energy use for “mining” cryptocurrency has increased continuously since 2016, even skyrocketing in 2020 and up The current level is 149 terawatt-hours (TWh), an all-time high.

Power planning 8 proposes 3 scenarios for power source development. The Institute of Energy (Ministry of Industry and Trade) has just released a report explaining the conclusions of Deputy Prime Minister Le Van Thanh on the national electricity development plan for the period 2021-2030 with a vision to 2045 (Planning for electricity development). electricity 8). In which, receiving opinions on reviewing the scale of power source development, reasonable power source structure compared to electricity demand in each period, especially in the period to 2030; In order to prevent unreasonable backup of power sources (such as the plan to develop the total installed capacity of 167GW of power sources by 2030, while the load demand is forecast at 86.3GW), the Consultant said Power planning. 8 proposed 3 scenarios for developing power sources to meet 3 scenarios of low load demand, base load and high load. The results of capacity balance of 3 selected scenarios show that renewable energy sources (wind and solar) have the proportion of 24% in 2020; 24-27% in 2030 and 38-42% in 2045 depending on the load scenario. The crude reserve ratio if including wind and solar is always high at 60-80%, but wind and solar power sources are variable renewable energy sources, contributing very little to power system redundancy, especially At the time of maximum load in the evening, there is no sun. Specifically, in the dry season, in the evening, when the national wind power occurs, it only reaches the guaranteed capacity (about 10% of the installed capacity for onshore wind and 20% of the installed capacity for offshore wind). ), at this time, the national crude reserve ratio of power supply will only reach 21% in 2020, 11%-14% in 2030 and 5%-8% in 2045 depending on the load scenario. The consultant said that in order to confirm the redundant or insufficient spare capacity, it is necessary to calculate the expected number of hours that do not meet the load demand. The calculation results show that the reserve scale as above ensures the reliability of the system’s power supply. The proportion of electricity from renewable energy sources (including hydroelectricity) in total electricity production of the selected scenarios all meet the objectives of renewable energy development in Vietnam’s Renewable Energy Development Strategy, reaching 32% in 2030 and 40.3% in 2045. According to the Institute of Energy, although the simulation of energy storage sources has been included, the minimum-cost planning model still chooses to cut a part of renewable energy to meet the flexible needs of the system instead. because investing in more storage resources, because investing in these resources will not be economically viable. The reduction rate calculated from the model is about 1.5% of renewable energy output/year (excluding cuts due to local transmission). The use of a partial reduction in renewable energy to meet flexible demand is used by countries around the world, and accepting a partial reduction in renewable energy is also one of the solutions. to develop renewable energy sources. At the request of ministries, agencies and appraisal councils, Power Master Plan 8 has included additional power source options that occur in addition to the above 3 scenarios to provide information for competent authorities to consider in determining the power supply. operating. In particular, the most difficult option to build power sources and grids is when there are risks of stacking, including high load growth and slow progress of thermal power sources (especially domestic gas exploitation sources). Accordingly, the proposal proposes to select the power source development scenario corresponding to the baseline load demand forecast, which is the selected scenario to calculate the design of the transmission grid, calculate economic and financial criteria. of Power Planning 8. At the same time, the project proposes a power source scenario corresponding to the forecast of high load demand to be considered for use in the management and development of power sources, ensuring to meet demand in the event that the national economy and electricity demand are met. load demand increased dramatically. In case of risk of stacking (high load, slow progress of coal-fired power sources, domestic gas-fired power sources), it will be necessary to add wind power, solar power, flexible power sources, etc. operate ICE to meet the demand for electricity and build more one-way lines from the South Central region to the North to transmit the capacity of power plants.

Meanwhile, there is an inexhaustible source of energy, which is solar energy, which is being used in many constructions serving human life. The use of hot water by solar energy has also been implemented, but in unstable weather areas such as central provinces, especially Quang Binh, it is difficult to apply solar energy to generate electricity. Year-round hot water for daily living. Two children Dinh Thi Kim Oanh and Kaohsiung Cuong with the structural diagram of a solar water heater product. To solve this problem, Dinh Thi Kim Oanh, a student of class 12B and Kaohsiung Cuong, a student of class 12A, Trung Hoa Middle School and High School together with teacher Dinh Ngoc Trai researched and manufactured ordinary products. hot water by combining a solar water heater with an electric water heater. The principle of operation of this device is: the output of the solar water heater will be put through the inlet of the electric water heater, the output of the electric water heater will be brought down to the faucet. to use. The electricity supplied to the electric water heater is controlled by a controller with a temperature sensor. The temperature sensor head is located in the heart of the solar water heater. If the temperature in the solar water heater reaches 40 degrees Celsius or more (this temperature value can be adjusted), the controller will control the relay to disconnect the power to the electric water heater. At this time, hot water from the solar water heater flows through the electric water heater and flows down the faucet for use. If the temperature in the solar water heater is lower than 40 degrees Celsius, the controller will control the relay to power on the electric water heater. At this time, the water from the solar water heater flows through the electric water heater, here, the water will be heated to a certain temperature (depending on the user’s adjustment) and flows down the faucet for use. . The amount of electricity used to heat the water will be less because the water in the solar water heater itself is already heated more than normal water (during sunny days or hot temperatures). According to Kaohsiung, the outstanding advantage of this product is that it has come up with a solution to use solar water heaters in unstable rainy and sunny areas, namely the combination of using between the solar water heater and the electric water heater in a reasonable way. The power supply to the electric water heater is controlled to close and disconnect automatically on the basis of recognizing the water temperature in the solar water heater. This is the outstanding feature of the product, which helps to maximize the amount of electricity used to heat water. Without this automatic controller, according to habit, users will turn on the attomat to have hot water but forget that that day, it was sunny and there was hot water in the solar water heater. This habit will consume an unnecessary amount of power. But if there is this controller, the power supply for the electric water heater is fully automatic and scientific, depending on the water temperature in the solar water heater. Only when the temperature of the water in the solar water heater is too low (below 40 degrees Celsius), then the controller will output a signal to the relay to close the electric lock to supply power to the electric water heater. to boil water. Currently, the demand for hot water in daily life is very large. Therefore, in areas with erratic rainy and sunny weather that must use an electric water heater, the monthly electricity consumption is not small. But if installed in combination with another solar water heater, can significantly save monthly electricity consumption. According to the current quote, a 130l solar water heater (for a family of about 5 people) costs from 3.7 million VND, with a warranty of up to 5 years, a lifespan from 10 years to 15 years. The low initial cost but can be used for a long time and help consumers use hot water all year round without having to pay a lot of electricity bills is the obvious economic benefit of the project. Moreover, solar energy is a clean energy source that does not pollute the environment, therefore, if the product of the project is widely used, it will contribute to environmental protection. “We are very confident with this topic, because after completing the project, we were facilitated by our parents to install it right in our family to use. We are ready to support and guide the design and installation stages for families who need to use solar water heaters. Hopefully, our project will receive the investment of businesses to make products that are both technical and cheap to serve the needs of the people,” shared Dinh Thi Kim Oanh.

Tulip turbines are “planted” in urban areas, on the rooftops of houses in Amsterdam, the Netherlands Traditional wind turbines are often located in the sea, are huge in size, make loud noises, can harm birds, and it is important that very strong winds are needed to generate electricity. The new tulip-shaped design overcomes all of the above shortcomings, it only needs a normal wind to generate enough electricity for a family to use comfortably all day. Israeli-American Dr Daniel Farb, the inventor of the tulip turbine, said the unique aerodynamic design makes the turbines quiet, efficient and capable of generating more than 50% of the electricity in clusters. Shaped like glossy flowers in a variety of colors and sizes (1m, 3m and 6m high), the tulip turbines are designed to double duty as electricity generation and artistic decoration on the rooftops. home, shopping mall, school… In addition, a solar system combined with tulip turbines could reduce overcrowding during the late afternoon peaks in many parts of the world when sunlight goes out and strong winds pick up.

Bitcoin digital currency. (Photo: AFP/VNA) On May 28, British police said they had discovered a case stealing electricity large capacity to mine the digital currency bitcoin. Specifically, in a dismantling of a cannabis plant, the anti-narcotics police force in England suddenly discovered an organization Bitcoin “mining” using a large power source to steal from the national grid. The facility is located in an industrial area in Birmingham – the UK’s second largest city. Through inspection, the police discovered about 100 computers dedicated to “mining” bitcoin. At the time the police arrived, there was no one at the facility. The case is currently under investigation. The digital currency “mining” system consumes a large amount of electricity, so some lines specializing in “mining” cryptocurrency in the world often choose to steal electricity to reduce costs and increase profits. According to Deutsche Bank, “mining” bitcoin alone consumes the same amount of electricity as Switzerland consumes each year. On May 12, the world’s largest electric vehicle maker Tesla (USA) announced that it would stop using bitcoin in its car sales due to concerns about environmental issues. CEO (CEO) of Tesla, American billionaire Elon Musk states: “Tesla stopped using bitcoin car sales. We are concerned about the growing use of fossil fuels for bitcoin mining and trading, especially coal – the worst-emitting fuel.” Iranian President Hassan Rouhani has announced a four-month ban on all crypto-mining activities after many major cities suffered power cuts due to power shortages.

Changing habits of saving electricity not only reduces costs for the family but also contributes to saving electricity in general. Although there are not many electrical appliances in the home, only using them in accordance with the needs and reasonable time will contribute to saving a lot of electricity. In addition, customers need to check and maintain the indoor wiring system to ensure reasonable science because if the wiring is confused, it will cause power consumption to be lost in the transmission process; at the same time properly use appliances that consume large electricity such as water heaters, irons, refrigerators, etc. Customer Le Diep Lai in Nguyen Nghiem ward – Quang Ngai city said: “My house has never left the air conditioner below 25 degrees, usually around 26-27 degrees. I find that to be appropriate, not much different from the outside, both protecting health and saving electricity. I also educate my children to turn off electrical appliances in the house when they do not need to use them. Vu Ha Ty customer in Nghia Dung commune – Quang Ngai city only uses the air conditioner when absolutely necessary and usually adjusts the temperature not too low to save energy. Ms. Ty shared: “My house is not located in the center, there are many gaps around, so I often use the wind and natural light in the house, minimizing the use of electricity to operate the cooling equipment. lighting”. Changing the habit of using electricity will save electricity, reduce costs for the family and contribute to saving electricity in general. Although there are not many electrical appliances in the home, only using them in accordance with the needs and reasonable time will contribute to saving a lot of electricity. Currently, customers can use the monthly electricity consumption estimator https://uoctinhdiennang.evn.com.vn to calculate the monthly electricity consumption of the family, thereby adjusting the usage. Use electricity in the most efficient and economical way. Propagate the use of electricity to the people. Huynh Trong Nguyen – Quang Ngai PC Business City recommended: “In addition to daily-life customers, manufacturing enterprises need to review and arrange reasonable production plans, minimizing the simultaneous mobilization of devices. consume large electricity capacity during peak hours and do not leave electrical equipment idle. This is the necessary coordination to ensure the stability of the infrastructure, and to ensure the supply of electricity for production and daily life in the dry season of 2021.”
In addition, to prevent local overload due to high demand for electricity, from the beginning of the second quarter of 2021, PC Quang Ngai also directed its affiliated units to regularly check lines and substations. Thanks to the initiative in the plan and the use of modern equipment such as thermal cameras, flycams, Quang Ngai PC was able to immediately detect and detect abnormal signs occurring with the equipment, preventing problems. can happen.
The economical and efficient use of electricity by customers is also one of the important solutions to help Quang Ngai PCs fight overload, reduce “heat” for the power grid system; thereby contributing to helping PC Quang Ngai perform well the management and operation of the power grid safely and effectively, improving the quality of power supply for customers.

According to analysts, Bitcoin is too expensive, causing investors to rush to find new digital currencies to profit. As a result, Ethereum has increased by more than 40% in value in the past April. Ethereum cryptocurrency was launched in 2013 with the purpose of being used to transact for an intranet of the same name. Now it is turning these crypto holders into billionaires with skyrocketing prices. The Ethereum cryptocurrency is also benefiting from the rise of NFTs, aka non-fungible tokens. This is a digital asset designed to represent ownership of unique virtual items such as art and sports memorabilia. Many NFTs like CryptoKitties and CryptoPunks are all running on Ethereum. However, this outburst of activity has resulted in congestion on the Ethereum network. Ethereum is currently being upgraded with the ambition of enabling faster transaction times and reducing the amount of power required to process transactions.

In order to prepare for the heat wave in 2021, Nghe An Power Company (Nghe An PC) has directed its units to quickly deploy the proposed solutions and scenarios to ensure electricity supply for the whole country. Nghe An province. Nghe An PC workers check outdoor equipment at Hung Hoa Substation (Nghe An) PC Nghe An information, during this year’s hot season in Nghe An, there will be many prolonged heat waves, leading to an increase in the demand for electricity for cooling than in previous years. It is expected that power output will increase, with an estimated capacity of about 820 MW. In order to ensure stable power supply in the face of increasing electricity demand in the summer of 2021, Nghe An PC has prepared a “scenario” carefully, with many solutions to supply electricity to people and businesses. Mr. Le Quang Thanh – Deputy Director of PC Nghe An said that 2021 is not expected to be as hot as the previous year, but despite the prolonged epidemic, most businesses in the area are operating stably again. power consumption is expected to increase. Regarding the load forecast, this year’s output growth will be higher than last year’s at over 12%. The most important and basic solution identified by the unit is to increase the power supply capacity, with the rapid completion of construction of substations and power lines for areas in the province. Accordingly, from the end of 2020 until now, Nghe An PC has built and installed hundreds of large and small projects, including: Raising the capacity of 110kV substation in Cua Lo route, increasing the capacity of 110kV Quynh Luu substation, completing upgrading the transmission line. 110kV from Quynh Luu – Quy Hop. Along with that, renovating and upgrading low-voltage trunk roads; replace the meter periodically; strengthening overhaul, cleaning of transmission lines and transformers; replacing the name plate number of the road, pole number, safety sign of the substation transmission line… and is implementing the plan to energize and put into operation 110kV Con Cuong substation, increasing the capacity of 110kV Hung Nguyen and Quy Hop substations in the month. 6/2021. After energizing, the station will power on in time to serve the people’s demand for electricity in the summer months; support stable and safe power supply in the area. However, according to PC Nghe An, the case of an unexpected increase in output through monitoring is unlikely and in fact, if it happens, the power infrastructure including medium voltage transmission lines, substations and power grids. low voltage will still be able to meet. Alternating power cuts to reduce capacity as announced by EVN will not happen, however, it does not exclude some cases such as: The power supply of the whole system is malfunctioning, incidents such as the breakdown of hydroelectric power units , the North – South 500kV transmission fault leading to failure to mobilize the grid capacity of the whole system will be automatically laid off. In addition, there is a problem of maintenance schedules of power plants (thermal power plants, hydroelectric plants) which can also lead to lack of power, requiring capacity regulation between regions. In the coming period, the vicinity of Nghe An will record a sudden increase in load, especially in Thanh Hoa area, and in Nghe An will also have a sudden increase at the end of 2021 when Hoang Mai 1 and Hoang Mai IPs WHA Industrial Park comes into operation. This is not only a problem for the electricity industry in Nghe An but also for the power system in the North as well as in the whole country. To solve it, EVN will have capacity coordination solutions to meet demand. Power supply scenarios have been developed at the transmission grid level (220kV, 500kV) in order to mobilize and balance capacity in the North – Central – South region. Thus, in the short term, the stable and continuous power supply for Nghe An will be ensured. PC Attention Nghe An Use electricity in hot weather PC Nghe An also noted that, in order for the power grid to operate stably during the peak of heat, it is necessary to coordinate and propagate propaganda at all levels of the government, local and central media agencies on the appropriate use of content. , saving. This content is very important for the national power system and grid, will avoid unnecessary grid overload due to unreasonable use, reduce the greenhouse effect, help limit environmental pollution, have a enough electricity to serve economic development for production and also save living costs for electricity users themselves. PC Nghe An continuously advises customers to avoid being subjective, negligent, not to misunderstand between electricity price and electricity consumption; Use electricity in the most efficient and economical way when entering the hot season. Just small actions from the people such as turning off electrical appliances when not in use, not using many large-capacity devices at the same time, using low-power consumption equipment labeled energy-saving by the Ministry of Industry and Trade. Industry and Trade inspection will help save electricity. PC Nghe An has prepared scenarios for electricity growth in hot weather Families should use air conditioners at a reasonable level of 26-27 degrees Celsius or higher and use fans in combination to reduce power consumption. When using a cold room, do not open the door often, do not use electrical appliances with heat-generating features in the room such as irons, ovens, electric kettles, and hot water heaters. Families have many rooms, when watching TV should focus on watching together, turn off all devices in neighboring rooms. Use electricity only when absolutely necessary, avoid using devices simultaneously during peak hours… For factories, make sure to use the correct capacity and load chart. Along with that, implementing a reasonable production plan, minimizing the mobilization of equipment and machinery with large electricity consumption capacity at peak hours. To minimize electrical equipment operating at no-load, key energy-using establishments must save at least 2% of electricity consumed per product unit per year. Advise customers to use electricity as committed to the electricity industry in terms of registered load and time frame, or reduce capacity when required by the electricity industry due to sudden increase in load… When purchasing new equipment, pay attention to use equipment with energy-saving certification label of the Ministry of Industry and Trade. Responding to the electricity sector, coordinating propaganda and recommending surrounding households to save together.

The company has automated the voltage and frequency adjustment of the power system to ensure power quality; Reducing the amount of electricity that cannot be supplied to customers, creating more revenue for the electricity industry; Reduce long distance transmission and optimize transmission grid loss. Modernizing the development of electricity meters and remote metering data collection systems has helped to collect complete data on customers’ electricity usage, timely detect problems of the metering system. count. This technology also helps the Company closely monitor the electricity usage mode of customers, especially large customers, and at the same time serve to calculate the unit’s power loss accurately as well as the power loss of the station. public in particular. In addition, the Company also encourages customers to actively adjust or change electricity demand during peak hours. Thereby, reducing the maximum capacity of the power system, reducing the overload of the grid, contributing to improving the economic efficiency of the power system. At the same time, it will also create conditions for the community to be more aware of electricity saving and efficient use of electricity, contributing to the protection of national resources. Ba Ria – Vung Tau Power Company has implemented many measures to reduce power loss With the unremitting efforts of all employees Ba Ria-Vung Tau Power Company in the control of power loss in particular, the rate of power loss continuously decreased from 2015 to 3.97% at 22kV level; in 2019 is 1.75% (including 110kV level) and in 2020 is an impressive number: 1.57% (including 110kV level). With the mission “ Electricity is one step ahead ”, BRVT Power Company has actively invested and upgraded the power grid system, ensuring safe and reliable power supply for tourist centers such as Thuy Van beach (Vung Tau City), Long Hai beach. (Dat Do district), Ho Coc – Ho Tram resort (Xuyen Moc district)… Every year, the Company focuses its capital to invest in preventing overload and strengthening the power grid; Electric islands for industrial shrimp farming, irrigation pumping stations to fight against drought, concave areas without electricity, removing fishing tackle… to meet the demand for irrigation for agricultural production and aquaculture. fisheries and tourism development in the province. Doing a good job of reducing power loss makes a lot of sense. help reduce production costs, increase profits for the company and increase the efficiency of production and business of the unit.

Illustration – Photo: Reuters. In a status line (tweet) on the social network Twitter on May 12, Tesla CEO (CEO) Elon Musk suddenly announced that this electric car company stopped accepting Bitcoin as a means of payment when customers buy a car. . This statement by Mr. Musk – who has expressed a pro-crypto stance – shocked investors and caused a sell-off. The reason the world’s second-richest billionaire gave for the reversal is the risks that virtual currencies pose to the global environment. Bitcoin price immediately dropped after Mr. Musk’s tweet was posted. At more than 7:00 am on May 13, Vietnam time, Bitcoin price according to data on Coinmarketcap.com page slipped below $ 50,000, down more than 13% compared to the time 24 hours ago. Many other “hot” virtual currencies also dropped sharply, such as Ethereum down more than 6%, Dogecoin sliding 14%… In February, Musk revealed that Tesla had poured $1.5 billion into Bitcoin and said the company would soon accept Bitcoin as a means of payment when customers buy a car. That information immediately pushed the Bitcoin price up 20%. By March, he said Tesla customers were able to pay with Bitcoin. In a tweet on May 12, Musk said Tesla will not sell a single Bitcoin, but instead intends to use Bitcoin for transactions as soon as Bitcoin mining moves to using other energy sources. more sustainable quantity. “We are also looking at other cryptocurrencies that use less than 1% of electricity like Bitcoin,” Musk wrote. Bitcoins are “mined” by competing high-performance computers solving complex math problems, and the process consumes enormous amounts of power. The source of electricity for Bitcoin mining is usually thermal power, especially coal-fired power plants, posing a great concern about environmental pollution. At current rates, Bitcoin mining pools used as much energy as the entire Netherlands in 2019, according to data from the University of Cambridge and the International Energy Agency (IEA). Musk himself is a supporter of virtual currencies, and his statements often cause cryptocurrency prices to fluctuate wildly. However, he is also an advocate of clean technology. “Cryptocurrency is a good idea in many ways, and we believe it has a promising future. But that can’t come with a huge loss to the environment,” Musk said. Bitcoin price movement in the last 7 days – Source: Trading View. According to blockchain analysis companies, Bitcoin could in theory be traceable, raising the possibility of “green” Bitcoins having a higher price tag. Stronger climate change policies by countries around the world can also help in this. However, some Bitcoin advocates say that the current financial system – with millions of employees and computers in air-conditioned offices – also uses an overwhelming amount of electricity.

According to CNN, billionaire Elon Musk said that Tesla will suspend plans to accept Bitcoin as a means of payment when customers buy its cars. The reason Musk gave is that using Bitcoin costs the environment. This is a completely opposite move after a few months Musk launched Bitcoin “to the cloud”. According to the billionaire: “We are concerned about using more and more fossil fuels to mine and trade Bitcoin, especially coal. Cryptocurrency is a good idea on many levels and we believe in it.” “That is a promising future, but accepting and using digital money cannot come with a hefty price tag on the environment.” Immediately after that, the Bitcoin price fell 5% just minutes after Elon Musk’s announcement. A few hours later, Bitcoin price even bottomed to just over $ 46,000 / 1 Bitcoin and then recovered slightly. The fact that Elon Musk publicly supports Bitcoin while claiming Tesla is a “green” company when it comes to making electric, eco-friendly cars has always been controversial. Photo: TL. Everyone knows that mining Bitcoin takes a lot of energy and pollutes the environment. Bitcoin miners consume a lot of power to solve mathematical equations, validate transaction codes to receive back a certain amount of money worked. Some calculations show that the total electricity consumption of Bitcoin miners in the world is equivalent to the total electricity consumption of Finland. The fact that billionaire Elon Musk publicly supports Bitcoin while claiming Tesla is a “green” company when making electric cars, environmentally friendly has always been controversial. However, the CEO also left open plans that Tesla will still use Bitcoin when it finds a cleaner source of energy. “Tesla won’t sell any Bitcoin and we intend to accept Bitcoin for transactions as soon as mining converts to more sustainable energy. We are also looking at other cryptocurrencies that use less. 1% of energy / transactions that Bitcoin uses “. This new statement by Elon Musk surprised many people because earlier in a statement on the social audio application Clubhouse, the billionaire said “Bitcoin is a good thing”, adding that he is “late” and perhaps out bought cryptocurrency 8 years ago. The richest billionaire in the world added that he should have bought Bitcoin eight years ago. “I have been quite slow. But at this point, I think Bitcoin is a good thing,” billionaire Elon Musk said. Is the “pump blow”? Bitcoin is not the only cryptocurrency Musk has pumped in in recent weeks. He has repeatedly praised Dogecoin through his Twitter account with 54 million followers. Dogecoin even dropped when Musk joined Saturday Night Live and said: “Recently, the prices of many cryptocurrencies like Bitcoin, Ethereum and especially Dogecoin have increased”. Musk’s last tweet before the Bitcoin-related surprise announcement was also a question to poll his followers to see if they wanted “Tesla to accept Doge as a means of payment”. Photo: TL. Earlier in February, Tesla publicly stated that it had spent $ 1.5 billion on Bitcoin investments. Later in April, records showed they sold 10% of their Bitcoin holdings, making a profit of $ 101 million. The move caused a few rumors to emerge, suspecting that there was some kind of fraud when Tesla bought Bitcoin, Elon Musk said like it and then Tesla sold it. Twitter user Dave Portnoy had a post that would have tagged Elon Musk on this. Dave used the word “pump” to describe Tesla’s actions on Twitter. He wrote: “As I understand it: Elon Musk bought Bitcoin then he blew up, praised Bitcoin. Bitcoin price increased. Then Elon Musk sold out and pocketed a lot of money.” Elon Musk then responded under this post, “Oh no, I don’t. Tesla selling 10% of its Bitcoin holdings is necessary to demonstrate Bitcoin’s liquidity as an alternative channel to hold money. face”.

Workers of Ha Tinh Electricity Company advise on how to save electricity to customers. When the weather is hot, most families use continuously cooling devices such as electric fans and air conditioners. According to director of EVNNPC Customer Care Center Nguyen Trong Phung, air conditioning is the main factor that makes electricity bills soar. Research shows that, during hot weather, due to the continuous use of air conditioners, electricity consumption will increase by 50% -60% on average. Through studies and experiments have shown, when the outdoor temperature increases by 1oC, the electricity consumption of air conditioners increases by 2-3%. The habit of the hotter it is, the more families let the lower room temperature inadvertently make the air conditioner work continuously, leading to increased electricity consumption. To help reduce costs and contribute to stable operation of the power grid, EVNNPC recommends that customers who use electricity need to have the best temperature between 26 and 28 degrees Celsius. In case of not cool enough, users can turn on add a combined blower, which will save about 2-3% energy compared to turning the air conditioner on at a lower heat level. In addition, not regularly cleaning the air conditioner is also a cause of wasted electricity. In addition to the proper use of electrical equipment, EVNNPC recommends that people not simultaneously use large capacity electrical equipment (electric stove, washing machine, heater …) during peak hours (including including the time frame from 11:00 to 14:00 and from 6:00 pm to 11:00 pm daily). EVNNPC will be responsible for checking, handling and satisfactorily responding to all comments and problems of electricity customers in 27 Northern provinces.

Recently, an investment of over $ 200 million has been made to build a mine in the US. This trend is increasing rapidly in North America, according to CoinShares chief strategy officer Meltem Demirors. In March, the US state of Kentucky also passed two bills to reduce taxes for cryptocurrency miners, in order to attract more local workers. With capital released, the construction of a large-scale Bitcoin mining industry in North America has never been so explosive. What happened? China now accounts for 65% of the global Bitcoin mining size, compared with just 7.24% for the US. The exact number may not be the same according to reports from the US and China, but the fact is that the US is far behind on this front. China accounts for 65% of the total global Bitcoin mining capacity (source: Cambridge University) In the early days of cryptocurrencies, American miners were still wondering if their hashrate was paid when contributing to the mining pool. In many cases, miners are paid less than their efforts. Since Bitcoin uses proof of work (PoW), the hash rate becomes what determines what percentage of the miner’s effort is paid off. Proof-of-Work ̣ (PoW) is a consensus algorithm created in the blockchain network, used to validate transactions and produce new blocks in the chain. Meanwhile, hash rate is a measure of the algorithmic ability of a cryptocurrency miner like Bitcoin. Because bitcoin mining involves solving algorithms to confirm transactions, it requires powerful equipment to help find the required hash in the shortest amount of time. But China started to exploit very quickly thanks to cheap labor and electricity prices without having to worry too much about external problems. The country currently leads the world, accounting for about 30% of hydroelectricity and 50% of its coal-fired power generation capacity. The problem of the environment In North America, any act of harmful to the environment is put on the radar of the activists. When the virtual currency craze exploded, Bitcoin mining, which consumes electricity and emits greenhouse gases, quickly became the focus of criticism. Meanwhile, electricity consumption for Bitcoin mining in China will peak at 296.59 TWh by 2024, according to Nature Communications. This exceeds total energy consumption in 2016 by Italy and Saudi Arabia combined. In March, the Bank of America criticized the consumption of one Bitcoin at a price of $ 50,000 for carbon emissions equivalent to 270 tons, equivalent to the internal combustion engines of 60 cars. The PoW mechanism causes Bitcoin transactions to require miners to compete for an algorithm to validate the block on the chain. In return, they are rewarded with Bitcoins for completing difficult problems. So, machines like the ASIC are specifically designed to do this, and they consume tremendous amounts of power. This is actually a security enhancement of PoW, not a bug. If the answers called hashes are too easy to solve, the blockchain network is vulnerable to attack by hackers. However, using a lot of energy isn’t necessarily a bad thing. A company called Crusoe Energy has developed technology to “capture” gas in the central atmosphere at oil wells and use it to power on-site data centers. The company deployed projects in Colorado, Montana, Wyoming, and North Dakota and resulted in a 72% reduction in CO2 emissions compared to burning it. Bitcoin mining is essentially power consuming because it runs 24/7 and needs stable and constant energy sources. Another advantage of Bitcoin is that it uses energy in places far from residential, like mining mines located in remote areas in Xinjiang, China. The big problem today is that Bitcoin is still using fossil fuels and enrich these companies. Only 39% of total energy consumption comes from renewable sources such as wind, water, and solar, according to research from Cambridge University. But even if Bitcoin mining runs entirely on renewable energy, it will create increasing demand for ASICs and disrupt the global supply chain of semiconductors. The end result is a pile of electronic waste that no single green energy source can deal with. The problem could be under control if the industry’s focus was shifted from China to the US, where environmental activists play an active role in curbing energy consumption and carbon emissions. school. Security risks? Aside from the environment, another danger lies in Bitcoin’s consensus mechanism with more than half of the network hashes located in China. That makes it possible for China to control the protocol and reverse transactions. This is a disgrace to Americans when the Internet revolution was initiated in the country of chess, but in the age of cryptocurrencies, China is in control of the game. Cryptocurrency attacks, known as 51% attacks, target a weakness in PoW’s consensus mechanism when a group of people has more than 50% of their hash power. In such attacks, the attacker does not actually steal the virtual currency, but just spends twice the amount he has by executing two transactions simultaneously to two different wallets and defrauding the system. But any exchange with good liquidity can prevent such an attack by setting a withdrawal limit. In the future, the competition of semiconductor chip factories creating more 4.0 shovels is expected to help this industry have global coverage. The end of PoW? Will the PoW mechanism be out of date? After all, Ethereum is emerging with the second largest market cap, preparing to move to a Proof-of-Stake mechanism that significantly reduces energy consumption and speeds up transactions. This mechanism makes it possible for one person to mine or validate block transactions by depositing virtual money into the network. This deposit is locked and returned to its owner after a set period of time, to prevent fraud. Even so, PoW in the 12 years of its existence has demonstrated its ability to prevent any cyberattacks. Meanwhile, PoS still needs time to experiment. Ethereum’s PoS transition phase, which is known as ETH 2.0, was planned 2 years ago and is expected to begin rolling out next July. The new hub of Bitcoin? Neither the US nor China, other emerging countries could soon outperform both thanks to more renewable energy and cheaper operating costs like India. America is thriving, but the gold mines in China cannot disappear overnight unless there are special government regulations. Experts expect that China can drop to 40-50% of the total hash rate within the next three years, and then North America could account for 30%, 20% from Europe and the remaining 10%. scattered in other areas. The problem with the US is that the federal government does not interfere and needs its own policies in states to attract and retain blockchain companies, as is the case with the state of Zug in Switzerland, which is known as the Valley. virtual money of the world thanks to specific policies of the state government. A miner is cleaning the ASIC Several states like Kentucky, Texas, and US cities like Miami are slowly recognizing blockchain as the technology of the future, and experts expect North America to win 10% of the global hashrate next year. Even so, as Bitcoin continues to receive investment, environmental issues will continue to be a major hurdle preventing the explosion of mining pools in North America, said the Hashrate Index expert Ethan Vera. The power failure in Xinjiang on April 16 affected the mines there and indirectly caused Bitcoin to lose 21% of its value from the peak of $ 64,000, possibly the strongest warning to the United States. in the war of cryptocurrencies, the future of humanity.

Turning on the air conditioner at the right temperature saves electricity Illustration When using the air conditioner, you need to adjust the temperature accordingly. Do not use the air conditioner at too low a temperature, while consuming electricity and harming health. According to calculations, every 5 degrees Celsius reduction, the air conditioner will consume about 40% more electricity. In addition, turning on the air conditioner together with turning on the fan will save 10 – 15% of energy consumption, regularly cleaning the filter, will save 5-7% of electricity. Do not place the device near the wall, as this will waste 20-25% of the electricity. Before leaving the room, turn off the air conditioner about 30 minutes or 1 hour earlier to reduce power consumption and cost of this summer-consuming equipment. Unplug electronic devices when not in use to save energy Illustration According to statistics, many electronic devices such as computers, TVs, sound systems, … still use electricity even when turned off. While these numbers are not high, consider that they consume you 24 hours a day and 7 days a week over a long period of time. Use LEDs instead of Compact lights to save electricity In terms of price, LED bulbs are much more expensive than Compact bulbs due to more modern LED technology. This is considered as one of the factors that make consumers hesitate in choosing to buy products. Illustration However, in terms of long-term economic benefits, LED bulbs will be more economical than Compact bulbs because using LEDs will save energy, significantly reduce monthly electricity costs and repair costs. , replace the ball. Pick up cool air from home windows and doors Perhaps the easiest way is to take advantage of the breeze when the weather is cool. Take advantage of the cool natural breeze, open all windows or doors so that the air can circulate, create a cool space, easily get a good night’s sleep without having to use a fan. or air-conditioning at maximum. Use wall paint, light-colored objects Illustration Color also plays a big role. Light colors are better for reflecting light. You can simply use 1 electric bulb to light up the room. Bright colors also reduce heat absorption and create a softer, cooler feeling for the home. Selection of heat-blocking curtains Illustration Using appropriate curtains will help protect against the sun, prevent heat and minimize the heat and discomfort in the summer. Types with light, fresh, youthful colors such as light green, light yellow, light orange, cream … are very popular. In addition, sunscreen curtains should also be used to reduce heat and block infrared rays.

Mr. Le Anh Duong – Deputy General Director of Hanoi Electricity Corporation (EVNHANOI) said that economical and efficient use of electricity is an important requirement in the context of a lack of power supply, especially at peak times. summer. Therefore, the propaganda on economical use of electricity has been deployed by the Capital’s electricity industry in many forms, such as through the online customer care system, organizing competitions, on the media … Meanwhile, the electricity industry implements technical plans, such as replacing all mechanical meters with electronic meters, combining daily metering database for each customer group …

Hanoi promotes efficient use of electricity

Specifically, in 2020, Vietnam Electricity (EVN) has built a website http://sudungdien.evn.com.vn, made a list of key energy users (customers with consumption rates). on average 3 million kWh / year or more) to monitor and recommend a reasonable and effective electricity use plan. As a result, in 2020, Hanoi has saved about 430.8 million kWh of electricity, equal to 2.15% of commercial electricity output, equivalent to about 870 billion VND.

In order to effectively implement the use of electricity economically, Ms. Nguyen Thi Thu Phuong – Head of Communication Department of EVNHANOI expressed, currently, the economical use of electricity still depends on consumers’ perception. One of the popular habits of people is not to turn off the lights when leaving the room or unplug the power plug when not in use. In fact, electronic devices, home appliances still consume energy when turned off but not unplugged. “The demand for air conditioning in urban areas is very high. Just each family can save about 10% of their electricity consumption by using equipment that applies new technology (such as inverter technology). the amount of electricity saved is not small, “said Nguyen Thi Thu Phuong.

Dr. Nguyen Quan, former Minister of Science and Technology, Chairman of Vietnam Automation Association, said that about 30% of electricity consumption is for lighting, including civil and public lighting. Saving half of the electricity used for this purpose is equivalent to not having to invest in building a power plant with a capacity of about 4,000 MW.

Focus on key solutions

Promoting electricity-saving solutions not only helps households, agencies and offices reduce costs, but also contributes significantly to ensuring electricity supply. Because now, Vietnam has to import coal for electricity generation and is expected to import liquefied gas by 2023. According to the report of the Ministry of Industry and Trade, with the scenario of an average growth of the gross domestic product of 7% / year, the energy demand by 2025 is 352 billion kWh and by 2035 is 506 billion kWh of electricity; which is equivalent to about 130,000MW of power capacity by 2030. This is a huge challenge facing the energy sector in Vietnam.

Information about the plan to implement the program of economical and efficient use of energy in 2021, Mr. Le Anh Duong said that EVN HANOI is continuing to synchronously implement propaganda measures to each household and operator. main career, production facilities … associated with technical solutions of operation, inspection and supervision. “For households, the electricity industry will coordinate with local authorities, launch the movement “Households save electricity, save energy”, striving for each district to have 500 households, each district has 300 households. typical household use of electricity. Currently, we are coordinating to organize Earth Hour campaign in 2021. This is an annual event that has the meaning of propagating extensively on energy saving.“, Mr. Le Anh Duong specifically stated.

In addition, the People’s Committee of Hanoi has issued the Plan No. 58 / KH-UBND on enhancing electricity saving in Hanoi city by 2021. Accordingly, the city sets a minimum saving target of 2, 2% of total power consumption. The City People’s Committee requires offices, offices, office buildings, schools, hospitals … to save at least 5% of the total power consumption annually. For restaurants, hotels, commercial service establishments, office complexes, apartment buildings, 50% of the capacity of advertising lighting, outdoor decoration must be reduced at night peaks as required by the establishment. local electricity authority …

The City People’s Committee also suggested that households use electricity in an economical and efficient manner, such as: Turn off electrical equipment when leaving the room, cut off the power if not using electrical equipment. The city encourages units and individuals to install rooftop solar power systems, hot water heating systems from solar energy to reduce electricity consumption …

For enterprises manufacturing, construction, the city proposed to give priority to the use of electrical equipment labeled with high efficiency energy; Use off-peak power reserve systems to use during peak hours. In addition, the installation of large-scale renewable energy systems is also a solution to reduce power consumption and even resell the power supply.

In addition, the City People’s Committee will provide technical assistance to the production, manufacturing, renovation and market conversion of vehicles, equipment, machines, production lines, construction works, and mats. public lighting, transportation, energy saving in households …; strengthening capacity for economical and efficient use of energy; Communication to raise public awareness about economical and efficient use of energy.

Since the company’s energy management system (Energy Management) came into operation in 2014, information on equipment operation and energy consumption has been reviewed and evaluated comprehensively. In fact, the plant’s lines are invested in many stages, asynchronous, so it is necessary to research to have appropriate solutions, especially related to synchronous lines and energy consumption, positive pressure. to use new techniques and technologies to use energy economically and effectively, improve the life of equipment and reduce costs.

In addition to internal issues such as promulgating regulations and instructions related to operating and using equipment to save energy, raising the user’s awareness into a cultural feature, the Company has implementing many renovation projects. Typically the major improvements are as follows:

Water supply system improvementPreviously, using only one upstream station and mixing pumps with different characteristics, causing energy loss, often having problems in the pump system and not meeting production needs well.

The renovation project is divided into 2 independent stations and connected in series: the upstream station reduces the pressure and increases the flow to supply part of the transmission line and the booster pump station is used for the required equipment. higher pressure. Each of these pumping stations includes a number of pumps with the same output and ensures the characteristics of parallel-connected pumps are equivalent and each station has 01 inverter pump as the main driver to automatically control the remaining pumps according to the applied pressure.

Always maintain the desired pressure in each area and optimize power consumption when demand changes to reduce power consumption in this area. The equipment’s age has also been markedly improved.

Install the inverter that controls the fan motor speed: To replace the flue air pressure control system with the previous inlet throttle.

When the power consumption is in proportion to the rate of 3 with the change of speed: N1 / N2 = (n1 / n2) 3 should show that in addition to the ability to respond to the fast system, the power consumption is very saving. After replacement, it was verified that power consumption decreased by more than 20% compared to before.

Replaced Russian 20/8 Piston Air Compressor: By Ingersoll-Rand R160 inverter controlled air compressor from USA to help adjust pressure as desired and save energy consumption.

Installation of low voltage compensation system: In addition to 6KV compensation, automatic compensation cabinets are installed for low voltage distribution stations; directly install compensation cabinets for AC motors> 22 KW, right near where the engine works; help to improve quality Electrical Power for the gear and reduce losses, reduce current through the switch for direct compensation motors.

Install the LEDs: For use areas with different requirements 150 lux, 200 lux, 300 lux, 500 lux, and have separate switches that are clearly communicated and specifically assigned.

Replace the oven ceiling with new materials: Previously made of heat-resistant concrete, there was a large heat loss with the temperature measured above 100 degrees C, the Company replaced with a new material with ceramic fiber, the temperature dropped to around 70 degrees Celsius and ensured ensure better life during work

Installation of aeration systems for filter towers: Helps to dispel the debris that clumps up that previous backwash is ineffective. Helping the filter towers always in effective working conditions, reducing pump power consumption due to reduced filter pressure and increasing the time to change filter material after 3 years instead of yearly as before, reducing production costs.

Renovation of replacement materials for cooling towers: The previous material is PVC with a short working time that must be replaced every 3 years and has a lot of dirt, reducing the heat exchange process is replaced by a Composite material (FRP) with better heat resistance. , no fouling and Splash Bar design to create turbulent and splashing flow for better exchange and cooling (the previous temperature through the Tower only decreased from 5-7 degrees, raised to 10-12 degrees C), reduce the power consumption for the cooling fan and the service life of the material is more than 10 years.

With a series of technical solutions above, energy audit results in 2018 show that energy management activities in Vietnam – Singapore Steel have achieved quite good indicators, power consumption and FO oil have both decreased. Specifically for electricity, from 2015 to 2020, auxiliary power will decrease from 21.70 Kwh / ton to 20.48 Kwh / ton of product; Electricity for production decreased from 97.97 KWh / ton product to below 86.79 KWh / ton of product. FO oil for billet baking in 2015 to 2020 will decrease from 32.50 liters / ton of products to 31.29 liters / ton of product.
